The working title of my PHD thesis is "Sanely shedding load", which, while
our work to date has made a dent on it, is a broader question, that also applies
to people and how we manage load...

... las, for example, I'm at least 20 messages behind on these lists
this week so far,
and I figure that thesis will never complete until I learn how to
write in passive voice.

I think the two pieces above, this list, evangelism, and working
results has made an
enormous dent in how computer scientists and engineers think about
things over the
last 7 years, and it will continue to percolate through academia and
elsewhere to good effect.

And your and jim's paper has 389 cites now:

I know, sadly, though, that my opinion about how much we've changed
the world, has more than a bit of confirmation bias in it.

I loved what uber did (https://eng.uber.com/qalm/)

I'd certainly love to see kleinrock taught not just in comp sci and
engineering, but in business and government,
as I just spent 3 hours at the DMV that I wish I didn't need to spend,
and a day where I could hit dice.com for
"queue theory" and come up with hundreds of hits across all
professions... rather than 0.
